Is there a portable equivalent to __attribute__((noinline))?

Question

C++ / C#

Actually, function inlining should be prohibited: together with instruction reordering, it causes crashes. There is a special attribute for gcc, but I would not want to limit myself to gcc, I would like to compile the studio with a clang and an Intel compiler too. Is a subject possible?
So far the solution is:

#if defined(_MSC_VER)
#define NOINLINE __declspec(noinline)
#else
#define NOINLINE __attribute__ ((noinline))
#endif

But I'm not at all sure that this is cross-platform enough.

Answer 1

In theory, this thing should be repaired by properly placed barriers ...

Answer 2

You have a problem somewhere else, and this is not a solution, but simply an avoidance of it.
There is no portable analogue in the standard. And Clang understands __attribute__((noinline)).
But if you really have all sorts of non-standard atomics there, then:
1. use standard atomics;
2. use ordered atomics;
3. use barriers (either for the processor, or only for the compiler asm volatile("":::"memory"););
4. find out why the compiler allows itself to do reordering around your assembler inserts or intrinsics. Compiler bug?
And then some link-time optimization will come and break everything again.
And yes, are you sure that you wrote your critical section correctly? And why?
